Space-time intersection: Why is the red code different from the yellow code?

What does the health code mean when it represents the intersection of time and space?

The concept of "time-space intersection" is the same as "time-space companionship", which means that my phone number is detected by the epidemic prevention system and stays in the same time-space grid (800 m *800 m range) for more than 10 minute, and any number stays for more than 30 hours in recent 14 days, then the found number is the time-space companion number, and I will be killed.

What is the health password of the space-time partner?

Code yellow or red team.

According to the relevant epidemic prevention regulations, there may be contact between time and space companions and infected people, so there is also a certain risk of infection. Red team or yellow code must be specified. When people are assigned to red team or code yellow, they need to report to the current community or CDC in time. The CDC should conduct an epidemiological investigation on the red and yellow code personnel to determine whether they meet the corresponding epidemic prevention regulations, and then decode them accordingly.
